HENRY FLINT, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO LOUIS A. STEBER, OF SAME PLACE.

PORTABLE COMBINED STEAM AND HOT-AIR RADIATOR.

SPECIFICATION forming part of Letters Patent No. 510,852, dated December 12, 1893.

Application filed December 30, 1892. Serial No. 456,741. (No model.)

To all whom it may concern.-

Beit known that I, HENRY FLINT, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in a Portable Combined Steam and Hot-Air Radiator, of which the folowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a radiator utilizing steam and hot air in conjunction; and my invention consists in features of novelty hereinafter fully described and pointed out in the claims.

Figure I illustrates a front elevation of my radiator. Fig. II is a vertical section through the steam-boiler, taken on line 11-11, Fig. 1V, illustrating the ascending and descending ends of the steam pipes. Fig. III is a vertical section through the steam-boiler, taken on line IIIIII, Fig. IV, illustrating the hot air tubes that extend from the fire -chamber through the boiler. Fig. IVisahorizontal section, taken on line IV-IV, Fig. V. Fig. V is a vertical section taken on line VV, Fig. IV. Fig. VI is a vertical, enlarged, detail section taken on line VIVI, Fig. I, through the fuel supply governor. Fig. VII is a vertical, enlarged, detail section, taken on line VII-VII, Fig. I, through the water supply reservoir.

Referring to the drawings, 1 represents the base of the radiator, within which the firechamber 2 is located.

3 is a burner for gas, gasoline or any suitable vapor, said burner having connection with a fuel supply pipe 3*, connected outside the radiator with the supply.

4 are doors providing access to the firechamber, and 5 are sheets of mica in said doors through which the interior of the firechamber may be seen without opening the doors.

Located above the fire-chamber is a steamboiler 6, the under flat surface of which boiler forms the top of the fire-chamber, making the boiler in direct contact with the fire. Connected to the boiler 6, at one side of the radiator, and with their ends extending just through the top of the boiler, are the steam receiving pipes 7, in which pipes the steam passes upward and across the radiator to the downwardly extending pipes 8, in which the .condensed steam is conveyed into the boiler below the water line. The arrangement of the pipes is clearly shown in Fig. II, where it u will be readily seen that the steam formed in the boiler, from the heatin the fire-chamber, will enter the pipes 7, and making the circuit to the pipes 8, escapes from the downwardly projecting ends of the pipes 8 below the Water line in the boiler, producing a continuous G11- culation. The outside series of the pipes 8 do not enter the boiler as the rest of the series, but pass directly through the boiler 6, across the fire-chamber 2, and again enter the boiler discharging beneath the pipes 7, the steam and water in such pipes under the boiler becoming thereby heated to a high temperature, by the direct contact with the fire, greatly increasing the volume of steam 1n the boiler, agitating the water, and producing more efficient circulation of the steam. I

Extending directly through the steam boiler 6 are tubes 9, that convey the hot air from thefire-chamber up into the radiator, between and around the steam pipes, distr1buting the heat evenly over the radiator. These tubes are inserted in the top and bottom of the boiler, with water tight connections, and besides carrying the hot air up within the radiator, they serve the additional purpose of the hot air in passing through them assisting materially in heating the water in the boiler 6, thereby very materially increasing the steam radiation.

When a burner, employing oil as the fuel, is first lighted, there is generally a large escape of gas and obnoxious fumes that escape from the burner and are not consumed, if there is no means of detaining such gases until they are consumed. To obviate this, the air tubes 9 assist very materially, as air will be drawn downward through the tubes to the fire chamber, and the gases retained in the fire chamber until consumed.

10 is a drum or oven, forming a heating chamber, above the steam boiler 6, and to which communication is had from the fire chamber by a central tube 11 passing directly through the steam boiler 6, in like manner to the tubes'9. Fitting in the upper end of the tube 11 is a cap 12 with openings 13 near its upper end, and a flanged plate 14 forming its top.

15 is an open chamber around the drum or oven 10, and egress is formed from this chamber 15 by a pipe 16. Then the burners in the fire chamber are first lighted, the cap 12 is preferably depressed, so that the openings 13 in said cap open into the chamber 15, and any obnoxious gases that may not have been consumed pass into said chamber 15, and out through the pipe 16, from where they may be carried outside the room by suitable connecting pipes running to a chimney or through the wall.

17 is a suitable door giving access to the interior of the drum or oven 10.

18 is a casing extending over the radiator, which is preferably of the form shown in Fig. I, its open sides allowing the free radiation of heat into the room.

19 represents a water supply pipe connected to the steam boiler, and to the other end of which pipe is connected a water supply reservoir 20, with a funnel 21 at its upper end. The admission of water to the supply reservoir 20 is had through a valve 22 and the water passes through a valve 23 from the supply reservoir to the steam boiler. As there is no exhaust steam from my radiator, there is very little supply of water required, and for this reason a very small supply is required to be kept in the supply reservoir, for, as will be understood, the steam passing through the radiating pipes condenses and the condensed water returning to the boiler again produces steam, the circulation being thus kept up indefinitely.

To regulate the amount of heat, and the consequent pressure of steam, I provide a regulator for the fuel supply pipe, said regulator being shown in Figs. I and VI, and the description of which is as follows:

24 is a valve in the fuel supply pipe, from the stem of which valve extends an operating arm 25.

26 is a steam pipe located above the water line in the steam boiler 6, to which pipe a cylinder 27 is connected and its upper end is closed by a cap 28 containing packing 29. Within the cylinder is a piston 30, provided with a piston head 31 on its lower end, said piston extending upwardly through the packing and cap on the upper end of the cylinder 27. On the upper outside end of the piston 30 is a plate or washer 32, with extending arms 33, to which arms 33 are connected the arms, 34E of a fork 35, whose lower, forked end 36 is connected to the valve arm 25.

37 are weights on the upper, reduced end 38 of the piston 30, through the medium of which the amount of heat in the radiator may be regulated; for it will be seen that the pressure of steam, if the heat becomes greater than the amount desired, and indicated by the weights 37, will, in pressing against the piston head 31, raise the piston 30 upward, carrying with said piston the plate 32, and con.- sequently the fork 35, thereby moving the valve arm 25 and cutting off a portion of the fuel supply frmnthe supply pipe, thus reducing the amount of flame in the fire chamber, and causing the heat and steam to diminish.

I claim as my invention- 1. In a radiator, the combination of a fire chamber, a steam boiler over said fire chamber, steam radiating pipes, and hot air fines 9 and 11 through said boiler, an oven, and a movable perforated cap 12 in said flue 11;

substantially as and for the purpose set forth.

2. In a radiator, the combination of a fire chamber, a burner in said chamber, a steam boiler over said fire chamber, steam radiating pipes connected to said boiler, hot air flues 9 and 11 extending through the boiler, an oven, and a heating chamber surrounding said oven; substantially as and for the purpose set forth.

3. In a radiator, the combination of a fire chamber, a burner in said fire chamber, a steam boiler, steam radiating pipes connected to said boiler, and flues extending through the boiler between the steam radiating pipes, and a flue 11 forming com munication between the fire chamber and said oven; substantially as and for the purpose set forth.

at. In a radiator, the combination of a fire chamber, a steam boiler, steam radiating pipes, one end of each of said pipes emerging from the boiler at a point above the water line, and the other ends of said pipes extending into the boiler, where a portion of them empty directly into the boiler below the water line, and the remainder of said pipes extending directly through the boiler and across the fire chamber and then emptying into said boilersubstantially as and for the purpose set forth.
